What should you know about advanced ovarian cancer symptoms?

The pattern differs between people and may change during treatment. Symptoms can come from the tumour, fluid in the abdomen or chest, pressure on nearby organs, reduced food intake, treatment effects or another condition.

Advanced ovarian cancer has extended beyond the ovary or ovaries to other tissues in the abdomen or farther away. Fluid called ascites can collect in the abdomen, causing tightness, increasing girth, early fullness and shortness of breath. Tumour deposits can irritate or press on the bowel and bladder.

People with advanced ovarian cancer may notice constipation, nausea, urinary frequency, back discomfort, reduced appetite, weight change or low energy. These symptoms also occur in many non-cancer conditions; their persistence, progression and effect on eating or normal activity guide the need for assessment rather than any single symptom proving the cause.

Tell the oncology team when a symptom began, whether it is constant, what makes it worse and how it affects meals, sleep, walking, urination or bowel movements. A brief daily record of abdominal swelling, pain, nausea, food and fluid intake, bowel activity and breathlessness can reveal a meaningful change.

Assessment may include an examination, blood tests and imaging such as pelvic ultrasound or other scans. Treatment can address both the cancer and its effects: chemotherapy or debulking surgery may be considered for the disease, while medicines, fluid drainage, nutrition support and palliative care may ease specific symptoms.

Get urgent medical help for severe or rapidly worsening abdominal pain, a swollen abdomen with repeated vomiting, inability to pass stool or gas, fainting, chest pain or marked breathing difficulty. These signs can occur with bowel blockage, a blood clot, fluid pressure or another acute problem.

Contact the cancer team without delay for fever during treatment, new one-sided leg swelling or pain, inability to keep fluids down, much less urine, uncontrolled symptoms or a sudden decline in alertness or mobility. Follow the emergency instructions supplied with your treatment.

Ask what is causing the abdominal swelling or breathlessness, whether fluid can be drained, how constipation and nausea should be managed, and which changes suggest bowel blockage or a clot. Request a clear contact plan for evenings and weekends and ask how symptom relief fits with cancer-directed treatment.
